After successfully using cmake port for long time, today I there was a failure with the message:

thomaspruschke@n0843:Skript> sudo port -up upgrade outdated

I tried (according to the Trac Guidelines) to uninstall and reinstall cmake, but it repeats the error message on install. I checked Apples Developer Website, but there is no JDK for Snow Leopard available (in fact, cmake never complained about this before). As I am using cmake quite intensively, I feel somewhat lost now ...

The message is correct. See #26934 for the full story.
